📘

Mini Lesson

Numbers up to one million appear in populations, distances, and large data sets. Every number can be written three ways: standard form (digits only), word form (written-out words), and expanded form (each place value shown as an addition).

The Place-Value Chart to 1,000,000

  • The seven place values from right to left: ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions.
  • Each place is 10 times greater than the place to its right.
  • Use commas to separate every group of three digits: 345,206.

Standard Form

  • Write the digits in order from greatest place to least.
  • Insert a comma after every third digit from the right: 1,234,567.
  • Example: three hundred forty-five thousand, two hundred six → 345,206.

Word Form

  • Name the millions group, then the thousands group, then the hundreds group.
  • Use a comma and the word "thousand" after the thousands group: "forty-five thousand, two hundred six."
  • Zero in any place is not spoken: 345,206 has no tens, so tens are not named.

Expanded Form

  • Break the number into the value of each non-zero digit and add them.
  • 345,206 → 300,000 + 40,000 + 5,000 + 200 + 6.
  • Skip any place whose digit is zero — no zero addends.
Vocabulary
Place value
The value a digit has based on its position within a numbere.g. The 4 in 345,206 has a place value of 40,000.
Standard form
A number written using digits only with commas every three placese.g. 345,206 is written in standard form.
Word form
A number written out using words instead of digitse.g. The word form of 206 is two hundred six.
Expanded form
A number written as the sum of the values of each non-zero digite.g. Expanded form: 345 = 300 + 40 + 5.
Million
A number equal to 1,000,000 — one thousand thousandse.g. A city of one million people is huge.

💡

Tip: group digits in threes from the right, then insert commas. Read each group (millions, thousands, then the rest) separately.

Guided Practice

Pick a word from the Trace menu and look carefully — after 5 seconds the ghost letters fade and you write the word from memory. Tap 🔁 Show again to bring the model back, or 🔍 Bigger for a fullscreen practice canvas.

Tracing Pad

Tip: Say each number aloud as you write it.

Now type any 3 different words from the Trace menu above. Look back if you need to — this is typing practice, not a memory test.
